1′-cyclobutyl-6-(4-piperidyloxy)spiro[benzopyran-2,4′-piperidine] derivatives with low nanomolar affinity for the human and rat histamine-3 receptors (H3Rs) are described. The spirobenzopyran piperidine ether analogs demonstrated excellent H3R affinity and selectivity against histamine receptor subtypes (H1R, H2R, and H4R), were stable in liver microsomes, and had selectivity against CYP P450 enzymes.
